SH UTTER-FASTENING.

SPECIFICATION fOr-ming part of Letters Patent 1\1'o.3EO,9E1l dated April 12, 887.

y Application filed July 1, 1886. Serial No. 206,798. (No model.)

To all whom t may concern: t, Be it known that I, JACOB WILLIAM KOEN,

a citizen of the United States, residing at Io art to which it appertains to make and usethe same, reference being hadto the accompanying drawings, and to letters of reference marked thereon, which form a part-of this specification.

which like letters of reference indicate correl spending parts in each of the several gures, Figure l isan elevation of a shutter or blind upon which is arranged the improved fastener. Fig. 2 is a sectional view of the same, showing 3o the fastener in elevation, with one of the shutter-plates removed. Fig. 3 is an elevation of the catching-lever e and the plate-section in which it has its bearings. Fig. 4 is an elevation showing the catching-lever d and its Fig. 5 is a side view or plan. Fig. 6 is an inside end view, and. Fig.-7 an outside end view, ofthe plate-sections together 5 and Fig. 8 is a plan of a lever or crank by means of which a certain finger-piece of the 4o catch may be depressed. Fig. 9 is a detail plan showing thev levers provided at their fulerums with lateral projections which engage one another and hold the body of the levers apart, so that there will be no excessive frictional contact.

In said drawings, a indicates a windowblind, and b a window-sill. Upon said blind are secured blind or shutter plates c c, which provide bearings for the catching-levers d e,

5o which latter engage the respective co-operating catches on the sill and outside of the house The object of this invention is to provide a terr-plate and said levers, and thus necessitated considerable labor, quantities considered, to adjust the parts and bring the catch into a condition for the market. In the present improvement the use of the pivotal pin and the process of drilling the plate to provide bearings for the same is avoided.`

The plates c c are formed in sections adapted to allow the introduction of the levers to their fulcrumal bearings, and when said levers arearranged on said bearings the sections are 'placed together, toprevent the longitudinal withdrawal of the levers.

The sections are composed principally of socketedparts c c2, the first of which is integrally provided with a fu'lcrumal lug, c3, for the inner lever and a stop-lug, c4, to limit the downward play of the lever e and prevent its withdrawal from the plate. Said part c is also provided with a curtain or guard, as at c5, to protect the lever from outside manipulation or prevent access thereto with an instrument.

At the outer end of the inner wall of the part c', andalso that of the part c", said walls are contracted, as at c6, so that a vertical slot, ci, Fig. 7, is formed of only sufficient width to allow a free passage and operation of the long or outer catching-lever. The inner ends of. the said parts c clz are provided with perforated flanges o8 es, which engage the inner face of the shutter or blind and allow the catch-plates to be securely fastened thereto. The face of said flanges is provided with a projecting hood, el, to protect the plate from an inflow of water, said hood being formed at the upper end of the slot over the levers as indicated in Figs. 4 and 6. The levers are thus protected or prevented in their vertical movement from being clogged by' ice. On the outside of said parts c c are formed grooves or notches c", Figs. 3 and 4, which coincide with each other in position and receive a binding-wire, cw, Fig. 5, by means of which the parts are held together prior to being placed in the hole or boring in IOO house.

the shutter. Lugs c, fitting into corresponding apertures, c, are provided, which eo-opcrate with the binding-wire in giving rigidity to the union of the parts. The socketed part c is also provided with a fulcrumal lug or bearing, el, for use in connection with the long lever (Z, said lug entering the notch d of said lever. Said part cL is also provided with a depending lug, c, which prevents the lever d from rising out of engagement with its fulcrum. rlhe said long lever, weighted at its outer catching end, d, is provided with a finger projection on its inner end, which differs from that of the device in the patent above referred to in that it has a lateral projection, d, Figs. 1, 4, and 9, extendingr in a direction away from the lever c, and thus presents a broad surface to the finger without interfering with the movement of the short or inner lever.

At the fulcrumal or notched centers of the levers the same are, or one of them is, provided with a projection or projections, (1*, by means of which said levers are held apart, so that there will be no danger of one of them being moved to any material extent when the other is operated by the finger.

To render it lunnecessary for the operator to extend his person out of the window to disengage the outer catches in closing the shutter, I have provided mechanism by means of which the same may be accomplished by simply thrusting the hand out to a point near the hinged edge of the shutter to a hand-piece, g, thereat arranged, which latter is connected by means of a rod, Zr, to an angle crank or lever, Z, Fig. 1. Said lever or crank isfulcrumed on the shutter, as at Z', near where the blind or shutter plates are secured, and has a depressingfinger, Z2, which rests upon the fingerbearing of thelonglever, as shown. By drawing on the finger-piece g the lever Z is turned on the fulcrum Z and the long catching-lever disengaged from its eo-operating catch on the The lever Z is provided with prongsor bearings Z, to prevent lateral movement of the depressing-finger and to secure a more steady and positive action.

It will of course be understood that the improved catches may be utilized independent of the depressing mechanism.

The operation of the catching-levers is practically the same as that in the prior patent, and further description on this point is deemed unnecessary.

I am aware that changes may be made in the construction of the device without departing from the invention.

Vhat I claim as new is- 1. The combination, with the catching-levers (Z e, of platesections, one of which has a curtain or guard, c, and both of which have fulcrumal bearings, substantially as and for the purposes set fort 2. Thecombinatiomwith thclever d, adapted to fasten the shutter in its open position, of a depressing-finger connected with and operated by a hand-piece, g, arranged on the shutter at a distance from the catch, substantially as set forth. 4

3. In a depressing device for releasing shutter-catching levers, the lever Z, having prongs or bearings Z5 and a depressing-finger, Z2, substantially as set forth.

4. In a shutter-fastening, the shutter-plate section c', having the fulcrumal lug c, stop c", guard ci, and flange c, all formed of one integral piece, substantially as and for the purposes set forth.

5. In ashutter-fastening, the combination of the shutterplate sections and independent catching-levers, the longer of which is provided with a finger projection, (.Z, which extends in a direction away from the shorter one, substantially as herein set forth.

6. In a shutter-fastening, the shutter-plates consisting of sections c' c, each of which has a lever-opening, and has also a faceflange, c, and a hood, cl", integral therewith, said hood formed above the lever-opening and extending from the face of said flange, in combination with catching-levers located'in the lever-openings, substantially as and for the purposes set forth.

7. The improved shutter-fastening combining therein the longer and shorter levers, the former of which extends entirely through the openingin the sectional shutter-plate,whereby it may be manipulated on both sides thereof, said levers being arranged side by side, and sections c c2, each provided with integral bear ings for the levers, which bearings coincide, the said sections being separable to allow the introduction of said levers to their respective bearings, substantially as and for the purposes set forth.

8. In combination with shutter-'sections c'c'i, separable from one another and each provided with fulcrumal bearings integral therewith, independent catchinglevers arranged side by side and provided at their fulcrumal centers with projections Z, by which said levers are parted, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of June, 1886.
